The reason is because the optimisation and automation means that there are no staff in the stores qualified to 'turn the knob' (and it is more complicated than that). What is the store to do, employ full-time knob-turners? They won't even pay for the uniforms of shelf packers or give them two toilet breaks on a shift.

How often do you think the knobs would need to be turned? You think someone or something is constantly fiddling with the temperature knobs of each individual freezer?

It is done automatically and continuously by the on-prem facilities management system, and monitored and adjusted remotely. If you disconnect the freezer from the control systems you need a meatbot to do the same work. Simplifying the problem to 'my kitchen freezer never needs to be adjusted, so the supermarket freezer can be disconnected' doesn't address the need.
